"It's something we're going to consider," manager Joe Girardi said. "It's something we've kind of thought about. You don't ever say [you'll keep it] forever, because a lot of it probably depends on how you perform. It makes sense to us."
Granderson had a productive season last year against left-handed pitching, but Girardi is offering a nod to Swisher's high on-base percentage against southpaws.
"Swish has had so much success, [if] you look over the last two years, against left-handers getting on base," Girardi said. "Grandy had a great year off lefties as well, but Swish has probably been on base against lefties more than any player we have, so I thought about flip-flopping them.
Over the previous two seasons, Swisher has posted a .428 on-base percentage against lefties, batting .310 (105-for-339) with 10 homers and 37 RBIs. For comparison purposes, Granderson had a .347 on-base percentage last year against lefties, slugging 16 homers and batting .272.
"Grandy has been extremely productive against left-handers, so [we could] get some guys on, and maybe Grandy pops one," Girardi said.
Girardi said that he still expects the left-handed-hitting Brett Gardner -- who was benched on Saturday, with Andruw Jones playing left field -- to play some games against left-handed pitching.
